A free new version of Gateway should be released for Infestation.
The terminals / consoles you hacked into in the campaign could be brought over into multiplayer for the Marines to use.
1.) Closes the main gate
2.) Turns the electric fence on
3.) Closes the door to the right (when facing the gate)
4.) Opens B02's outside door (more doors within could be opened / closed / destroyed)
5.) Opens B03's outside door (more doors within could be opened / closed / destroyed)
6.) Opens B04's outside door (more doors within could be opened / closed / destroyed)
7.) Opens the main command center (B01) door (more doors within could be opened / closed / destroyed)
8.) Turns on all the lights within the compound and inside the buildings (located within command center)
9.) Enable sentry turrets (computer located behind sentry turrets, once enabled cannot be disabled, able to be permanently destroyed by Aliens)
30 Alien tail hits and the prompt to open appears.
Once prompt to open appears for Aliens, door becomes unusable by Marines.
Once Alien rips open door it becomes destroyed permanently.
All doors could be destroyed besides the main gate.
Short timer to prevent door spamming.
Bring back the vents within the buildings and the underground sewer vents. In function, they would be similar to the holes in the floor on Pyramid. Just bring it over from the Alien campaign and add it.
A.I. Marines could even be placed within the buildings to help guard them. One on the bottom floor of B01, one on the top floor of B01, one on the bottom floor of B02, one on the top floor of B02, one in B03, and one in B04, all armed with Pulse Rifles or Shotguns. We have Survivor mode, so we can't we have Marines simply stand guard at designated locations and fire at will at any Aliens they detect?
Bring them back.
Bring them back.
Instead of Aliens destroying each light individually, the two outside generators could be disabled instead.
Scatter a few of them around outside for some explosive fun?
Disabled at the start. One just outside the command center door, one angled down the tunnel / corridor to the right, and the final one facing towards the wrecked Marlow ship.
Don't want sentry turrets? Disable them.
Want A.I. Marines? Enable them.
Give us more options. We have none whatsoever right now.
On each map, there are about one to three could spots to hold out on for Infestation. Instead of backing into a corner, I want more. All that above^ is what I want.
None of this will happen, but I can still dream.
